Albin Alfred Baeumler (sometimes Bäumler; German: [ˈbɔʏmlɐ]; 19 November 1887 – 19 March 1968), was an Austrian-born German philosopher, pedagogue and prominent Nazi ideologue. From 1924 he taught at the Technische Universität Dresden, at first as an unsalaried lecturer Privatdozent. Bäumler was made associate professor (Extraordinarius) in 1928 and full professor (Ordinarius) a year later. From 1933 he taught philosophy and political education in Berlin as the director of the Institute for Political Pedagogy.

After studying philosophy and art history in Berlin and Bonn, Baeumler received his doctorate in Munich in 1914 with a thesis on the problem of general validity in Kant's aesthetics. From 1924 he taught at the Technical University of Dresden, habilitated there and became associate professor in 1928 and full professor in 1929. In 1933, he was appointed by the National Socialist Prussian Minister of Culture Bernhard Rust to a newly established chair of philosophy and political pedagogy at the Friedrich Wilhelm University of Berlin, without the faculty's involvement, and at the same time director of the newly founded Institute for Political Pedagogy. Victor Klemperer commented on the appointment: "Poor Berlin faculty: Baeumler their philosopher, Neubert their Romanist." Alongside Ernst Niekisch, with whom he was a close friend, he had contributed to the first volumes of the journal Widerstand. He contributed to the Zeitschrift für nationalrevolutionäre Politik under the pseudonyms "Leopold Martin" and "Wolf Ecker".

Baeumler was originally close to the Bündische and the Jungkonservativen, but then turned to National Socialism. In 1930 he was a co-founder of the Völkisch and antisemitic Kampfbund für deutsche Kultur. From the beginning of the 1930s, he had personal contact with Hitler and the "Nazi chief ideologist" Alfred Rosenberg. At the Reichstag elections of 1932, Baeumler openly declared his allegiance to the NSDAP along with other philosophers, but it was not until after the party had come to power that he applied for membership.

On 10 May 1933, Baeumler gave his inaugural lecture, "Wider den undeutschen Geist" ("Against the Un-German Spirit"), as part of his college "Wissenschaft, Hochschule, Staat" ("Science, University, State") in the crowded lecture hall 38 of the Friedrich Wilhelm University. Most of the students had turned up in SA uniforms. At the beginning of the lecture, a student flag delegation marched in with the swastika banner. The little-noticed key quote from this lecture was as follows: "Politics can only be made by those who are responsible for it. There is indeed a philosophy and science of politics, but not a scientific politics and just as little a political science. Thought must answer to thought." Baeumler went on to explain: "In a word, it can be said here what National Socialism means intellectually: the replacement of the educated by the type of soldier." The "epoch of freedom of conscience, of individualism" was over. "They are now going out to burn books in which a spirit foreign to us has used the German word to fight us. [...] What we dismiss from ourselves today are poisons that have accumulated in the time of a false toleration." Later, the procession of torchbearers - but without Baeumler at the head - formed up to the Opernplatz. There, according to the Völkischer Beobachter, the "German spirit" was to be symbolically purified by burning 20,000 books.

In 1934, Baeumler demanded the "political soldier" as a student ideal, the establishment of "men's houses" and the exclusion of the "feminine-democratic". Martin Heidegger criticised what he perceived as a lack of depth in both Baeumler and Ernst Krieck, and that both wanted to realise the national pedagogical model of the "political soldier" through external training programmes and military training. Since July 1934, Baeumler had been a member of the NSDAP's Higher Education Commission. In 1934, Reichsleiter Rosenberg also appointed him "Head of the Office of Science of the Führer's Commissioner for the Supervision of Intellectual Training and Education of the NSDAP", and in 1941 he was promoted to Head of Service. Baeumler worked there primarily as Rosenberg's liaison to the universities and also edited the Internationale Zeitschrift für Erziehung and, from 1936, the journal Weltanschauung und Schule, whose editor was Hans Karl Leistritz. His task in the Rosenberg Office, Science Department, was in particular "to work on the assessment of humanities scholars to be appointed to universities and to deal with the fundamental questions of pedagogy."

For Adolf Hitler's 50th birthday in 1939, Baeumler wrote an article in the Festschrift Deutsche Wissenschaft. At that time, Ernst Krieck and Baeumler were considered "the two leading philosophers of National Socialism". From April 1942, Baeumler was head of the "Aufbauamt der Hohen Schule", a planned party university called the NSDAP's Hohe Schule.

After 1945, Baeumler was interned for three years in camps in Hammelburg and Ludwigsburg. He was one of the few Nazi professors who did not return to a university post.

One of Baeumler's more well-known texts is "Hellas and Germania", published in his 1937 book, "Studies in German Intellectual History". The basic thesis of this text is that any renewal for Germany, and indeed the West in general, would require a recovery of the values which permeated Ancient Hellas. As with much of his work, Baeumler made use of Nietzsche's legacy to lend force to the thesis of the article. Baeumler summarised his thesis thus:
